Nature and scope of the work

A reasonable assurance engagement involves the implementation of procedures aimed at obtaining evidence regarding the Information. The nature, timing, and extent of the procedures selected are within our professional judgment, particularly our evaluation of the risks that the Information contains significant misstatements, whether they result from fraud or error. In assessing these risks, we have taken into account the relevant internal control for the preparation of the Information by the Entity. We also :

• assessed the suitability of the Guidelines in terms of its relevance, comprehensiveness, reliability, neutrality and understandability taking into consideration, if relevant, the best practices of the industry.
• performed, on the Information:
• analytical procedures to verify the correct consolidation of the collected data as well as the consistency of their evolutions;
• detailed tests based on samples, to check the correct application of the definitions and procedures and reconcile the data with the supporting documents. This work was carried out with a selection of contributing entities listed below:
  • for the selected social Information: activities in China, Mexico and Italy, which cover 21% of the group’s workforce;
  • for the selected societal Information: the headquarters of the entity that centralizes all information;
  • for the selected environmental and health and safety Information: Belgium (Libramont), Brazil (Sao Paulo), Canada (Florence,Montreal, DC Ville Saint-Laurent), China (Suzhou), Spain (Burgos, DC Burgos), United-States of America (DC South Brunswick,Piscataway, North Little Rock, DC North Little Rock), France (Vichy-LRP, Mourenx), Italy (Settimo), Japan (Gotemba), Poland(Warsaw, DC Blonie), Turkey (Istanbul), representing 47% of Group activity (in units of finished goods reviewed). This work covers between 25% and 53% of the consolidated data selected for these tests (25% of hours worked by L'Oréal employees, 29% of work-related accidents, 45% of CO₂ emissions according to the “location-based” method, 43% of total waste, 53% of net water withdrawal).

We consider that the sampling methods and sample sizes we have selected through our professional judgment allow us to provide a reasonable assurance conclusion. However, due to the use of sampling techniques as well as other inherent limitations in the functioning of any information and internal control system, the risk of not detecting a material misstatement in the Information cannot be completely eliminated.

We believe that this work enable us to provide reasonable assurance that the Information has been prepared, in all material respects, in accordance with the Guidelines.
